 合闸线圈1VCF339752S6918可实现远方控制断路器合闸此脱扣器交直流电源通用操作。可由脉冲或持续命令触发。当命令为脉冲形式时，*短脉冲电流持续时间应不小于100 ms。合闸脱扣器的电气和操作特性与并联分闸脱扣器MO1完全相同。
只有在断路器和接地开关处于分闸位置时断路器手车才能从试验位置摇进到工作位置
• 断路器只有在工作位置或试验位置才能被合闸（机械闭锁，同时还有电气闭锁以防止电动合闸）当没有二次电源时，断路器只能被手动分闸（闭锁电磁铁）
• 断路器只有在试验位置时，二次插头才能被拔出
• 接地开关只有在断路器处于试验位置或被抽出后，才能被合闸
• 断路器处于合闸位置时不能从工作位置摇出到试验位置
• 还可另外选择附加的闭锁功能，如手车和接地开关操作机构闭锁电磁铁。
